add-apt-repository ppa: gives me errors [duplicate]

Я новичок в Ubuntu (12.04.3). Я пытаюсь установить handbrake и попробовал около 6 различных способов, которые, кажется, не работают, так что теперь я прошу помощи.

Шаг 1 sudo add-apt-repository ppa:stebbins/handbrake-releases

$ sudo add-apt-repository  ppa:stebbins/handbrake-releases
Traceback (most recent call last):
  File "/usr/bin/add-apt-repository", line 128, in <module>
    ppa_info = get_ppa_info_from_lp(user, ppa_name)
  File "/usr/lib/python2.7/dist-packages/softwareproperties/ppa.py", line 84, in get_ppa_info_from_lp
    curl.perform()
pycurl.error: (35, 'gnutls_handshake() failed: A TLS packet with unexpected length was received.')

Я получаю ошибку, что означает эта ошибка и как ее исправить?

В файле /etc/apt/sources.list у меня вот это

##ppa:stebbins/handbrake-releases
deb http://ppa.launchpad.net/stebbins/handbrake-releases/ubuntu quantal main
deb-src http://ppa.launchpad.net/stebbins/handbrake-releases/ubuntu quantal main

Если я проигнорирую ошибку и продолжу.

Шаг 2 sudo apt-get update

Я получаю.

W: Failed to fetch http://ppa.launchpad.net/stebbins/handbrake-releases/ubuntu/dists/oneiric/Release  Unable to find expected entry 'deb-src/binary-i386/Packages' in Release file (Wrong sources.list entry or malformed file)

E: Some index files failed to download. They have been ignored, or old ones used instead.

Опять же, если я проигнорирую сообщение

и продолжу.

Шаг 3 sudo apt-get install handbrake

Я получаю.

Package handbrake is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

W: Duplicate sources.list entry http://ppa.launchpad.net/stebbins/handbrake-releases/ubuntu/ oneiric/main i386 Packages (/var/lib/apt/lists/ppa.launchpad.net_stebbins_handbrake-releases_ubuntu_dists_oneiric_main_binary-i386_Packages)
W: You may want to run apt-get update to correct these problems
E: Package 'handbrake' has no installation candidate

Если я использую sudo apt-get install handbrake-gtk

я получаю следующее.

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
